Study on the cost composition and control of coal power in China under the perspective of policy evolution

The direction of China's power supply side to cleaner transformation has become a foregone conclusion, the future will mainly rely on new energy and renewable energy, coal-powered units will gradually from the main power supply to the regulating power supply, standby power change. However, due to China's special policy background and the annual rise in coal costs, China's coal power prices have long been subject to high-cost squeeze, cost-price linkage failure one after another, the survival and development of coal power has brought great risks and challenges. Research shows that the policy changes experienced by China's coal power is the primary reason for its cost system composition and price formation. Therefore, this paper takes the evolution of China's coal power reform policy as the entry point for research, reanalyze the cost composition system of coal-fired power and summarize its impact on the cost of coal-fired power, and puts forward suggestions on cost control in the dimension of sustainable development of coal power, which provides an effective reference to the planning and deployment of solving the predicament of transitioning coal power and narrowing down the profit loss.
